How to Use These Notes

01

Regular Study

Read each topic section fully. Study the diagrams, understand the examples, and note the "Exam Tip" boxes. Do one topic per day for best retention.

02

Last Night Prep

Focus on: "Last Night Tip" boxes, tables, and "Key Takeaway" boxes at the end of each section. The tables and diagrams give you the maximum information per minute.

03

Exam Day

Always start answers with the definition (concept box). Add diagrams wherever possible — figures earn extra marks. Use real-world examples to show depth.
